Hurricane Irma has strengthened to a Category 5 storm and catastrophic damage is possible in the Florida Keys and southern Florida this weekend, as a second storm has formed behind it.
Irma was packing 185 mph winds and gusts up to 220 mph as of before 2 p.m. ET Tuesday and is expected to continue churning with deadly hurricane-force winds and a dangerous storm surge across a wide swath of the Caribbean this week before moving toward southern Florida, according to the National Hurricane Center (NHC).
